NAT1 and triple-negative breast carcinoma: Different studies demonstrated that the 3′-untranslated region of NAT1 is a direct target for miR-1290 (Endo et al., 2014), and miR-6744-5p (Malagobadan et al., 2020), where its expression is downregulated, promoting distant metastasis in triple-negative breast cancers (Butcher and Minchin, 2012).
